Basin & Petroleum Systems Analysis

Fully integrated 1-D, 2-D and 3-D Basin & Petroleum Systems Modelling, providing a highly powerful, iterative and cost-effective solution to address subsurface uncertainties

Basin & Petroleum Systems Modelling (BPSM)

Key objectives

Integration: BPSM utilises key aspects of geological, geophysical and geochemical interpretation into a unified, integrated subsurface model
Powerful insight: Modern basin models can predict the spatial distribution, phase and composition of subsurface fluids, with stochastic uncertainty analysis a common tool
Flexibility: Workflows vary depending on the questions to address and data availability. Both top-down and bottom-up approaches are advocated, ideally with a combined hybrid methodology
Interdisciplinary: Applications for BPSM have been focussed on oil and gas exploration and production, but are increasingly domain agnostic, with recent developments to CCS, geological hydrogen, mining and geothermal energy.

Aims & objectives of BPSM

Common questions

What is the source rock potential?: Predict the spatial and temporal variability in source rock maturity and (when properly integrated with geochemical interpretation) the petroleum generation/expulsion volumes and phase
What volume and phase will be in my prospect?: Integrating source maturity through time, migration routes (e.g., fault seal), reservoir properties, PVT conditions and alteration processes (e.g., biodegradation) allows an estimation of prospect volumes and phase in both deterministic scenarios and stochastic uncertainty analysis
What are the critical elements/uncertainties?: IGI's workflow always includes risk & uncertainty analysis with distributed ranges of input parameters (e.g., TOC, geothermal gradients), dynamically showing which elements are most sensitive to predicted charge volumes and phase
How and why does heat flow vary across the region?: Coupled thermal-burial histories are fundamental to BPSM, integrating tectonic, sedimentological and fluid properties, calibrated to temperature, pressure and palaeothermometric (e.g., vitrinite reflectance) data
Surely basin modelling is expensive?: For most projects, even building a grid-based 3-D model is a relatively efficient process, providing impactful and powerful results in what is usually a fraction of the time taken for seismic and geological interpretations
How do we keep our model up-to-date?: Project deliverables include key outputs (e.g., digital maps for GIS/Petrel). Modelling files are also included to be updated as and when new data become available
